' Application filed March 17, 19265 Serial No. 95,226.

This invention 'relates t'o Aa machine for skivin-g a counter-first along one longitudinal edge and then -alongthe opposite edge, the,

counter. being first moved inv astraightpath through a portion of the machinewhi-le vits straight edge portion is lbeing skived, and .then 'in a diiferent` and irregularV path while its opposite edge portion, including its Lend portions, are being skived. A machine' organizedto'skive the two edge portions during a'continuous pass of the counter through the machine, ishereinafter referred to' as the Stewart machine, and is disclosed 'by the Stewart PatentV No. 653,892 datedlJuly 17,

The invention relates to thestraightedge skiving portion'of the Stewart machineand is embodied inthe improvements hereinafter described andclaimed.-

Of the accompanying drawings forming a part of this speciiication, 'i

Figure 1 is a top plan view of the flanged yoke, the deflecting roll, and two of the topguidingl rolls, yhereinafter described, constituting membersof the Straight edge Skiving portion. Y f

Figure 2 is an edge'view of the same.

Figure 3 shows in side elevation, the straight edge skiving portion including the members shown by Figures 1 and 2. l

Figure4 is a top Yplan view of the straight edge skiving portion omitting the rolls shown at the left in Figure 3. f

Figure 5 is a plan view of a skived counter.

The same reference' characters indicate the same parts in all ofthe figures.

12 designates the skivifngr knife which i. forms the straight skived edge portion 13 of a heel counter 16.; The'knife is fixed to the. frame. 14 adjacent to the nip of a pair` of driven feed rolls V15, which engage the counter 16 and force it in a straight path against the knife. Journalled iny fixed bear-V ings on the frame are a front lower guide roll 17 and a rear lower guide roll 18, said rolls being arranged as shown by Figure 3 to support the skived portion of the counter, and positively driven with the feed rolls, the direction of rotation being indicated by arrows in4 Figure 3. Between the front and rear rolls is a similarly driven intermediate guide roll 19. 20 designates a swinging yoke pivoted on a stud 21 supported by standards 22() on -the frame. The neckportioncof the yoke 'is providedwith a flange Vwhich `over-Y hangs the spaceV between the: skiving knife v'1 2and the front guiding'roll 1.7. 23 designates a loose front upper guiding roll', hav- Ving trunnions 2%1 journalled 1n bearings inthe yoke 20 and arranged to hold the counterin Contact with'the front `lowerroll 17, down- -ward pressure' being exertedon th'e'yokeby A 26 `designatesa krear upper 'a spring 25. n guiding roll journalled,V in: bearings: in yoke arms 27 ,mounted to swing onthe studE21j.' Therear upper roll isarranged .to hold the counter in contact with' the rearv lower roll 18, downward pressure being exerted on. one

[of theyoke arms by Vafsprfing 28.Y Between Athe front and rear rolls'23 and 26 is ',anintermediate upper roll 29 journalled in bearings` Ain the swinging ends of yoke arms 30, which are pivotedgont-he trunnionSZe.'A The intermediate upper rollis 'arranged' to hold.A the' counter in contact with the intermediate y lower roll 19.

`When the straight edge 13 Aof a long couni ter is being skived, it is desirable that-the lupper rolls 23 and 29 be held in a raised position so that they will not press the coun-` ter against the lower rolls 17 and'19; To

this end an adjustable support 31 is provided, which is verticallyv adjustable on a fixed member 32 of the frame, ,andis ar lranged as shown by Figure 3 to bear onV the Vunder-Side of the flange 22. .The supporty 'y 31 is secured to the member 32 by a screw 33-'passing through a vertical slot 34 in the stop. The` support may therefore-*be adp `justed upward to maintain the upper roll 23 in a'rraised position and prevent it from pressing the counter against' the roll 17.

There is also provided, as in the Stewart machine, a pin 38 constituting a support vwhich may be inserted in coinciding orifices inthe yoke 20. and one of the yoke arms 30, the arrangement being such that when the pin is inserted, it supports the roll 29 in a raised position and prevents it from pressing.

the counter a ainst the lower roll 19. V The counter there ore,-bears 'loosely on the rolls until it reaches the rear rolls 18 and 26 which are constantly in position to nip the counter.

The counter bulges upward from the skiv ing knife 12 toward .the flange 22, and, when .the rolls 23 and 29 areraised, the counter,

17and 19 and isy not otherwise controlled wise before its forward end is controlled by the rear rolls 18 and 26. To prevent this ,'liability, I provide a deflecting roll 35 having'trunnions 36 journalled in bearingsy 37 0n the under side of the flange 22. The roll 35 project-s considerably below the Vflange and its rolling contaotwith the counter prevents the latter Vfrom deviating Vfrom a straight course. When a shortl counteris toV be skived, the support 3l is lowered and the pinl 38 is removed to permit the rolls 23 and 29 to press the counter against the rolls 17 and 19. VThen this; is done, the deflecting roll 35 acts only to direct thel forward end of the counter to the nip of therolls 17 and It will be understood that the-portion ofl the machine, which forms the skived portion 'la'on the upper edge of the counter. may

be asV shown and described in the Stewart patent. Y Y Y c v The present invention is differentiated from the Stewart machine chiefly by the support 3l and thedeflecting roll 85, the support or pin 38 being'present inthe Stewart prising a skiving knife, driven feed rolls adapted to Vforce a countery against a knife, driven lower guiding rolls journalled in fixed Vbearings' and including a forward, a rear, andan intermediate roll, a pivoted yoke having a flange overhanging the space between the `skiving knife and the forward lower roll, a forward loose upper roll ournalled in said yoke and pressed toward the forward lower roll, a rear loose upper guiding'rolljournalled in pivoted yoke arms and pressed toward the rear lower roll, an intermediate loose upper guiding roll journalledVv in pivoted yoke arms and pressed toward the interme- 'diatelower roll, movable supports adapted 'to support the forward and interi'nediate f upper rolls inv raised'inoperative positions and to permit said rolls to assume their operative positions, and a deflecting; roll journalled in bearing on said flange and arranged te bear on theV upper side of the counter between the skiving knife Vand the forwardlower guiding roll, said deflecting roll being adapted to prevent edgewise displafiement of the counter when the forward vand intermediate upper rolls are raised,

In testimony whereof I have'aixed l yimmer n. Monsn.
